In the drawings, wherein is shown for purposes of illustration, merely, one embodiment of the invention, A designates the improved casement window generally. The improved window structure includes a rectangular window frame l which is set in a window opening B formed in a wall C, said window frame being composed of top, bottom, and side frame members which are suitably joined together to provide the rectangular window frame. The particular window frame illustrated in the drawings is made up of frame members of the cross-sectional shape shown to good advantage in Figs. 2, 3, 4, and 5; that is to say, each frame member of the window frame member includes an inner leg la which is` ush with the inner face of the wall C, an outer leg lb which is ush with the outer face of said wall C, and a transverse leg Ic which joins the legs la and Ib (see Figs. 2 and 3). At one side `of the window frame l, the left-hand side as the im-` proved window structure is illustrated in Figs. l, 4, and 5, said window frame is provided with a pair of hinge members 2,` Voneof said hinge members being welded, or otherwise secured, to

the `window frame at the topthereof and the l other of said hinge members being similarly secured to the window frame at the bottom thereof. The hinge members 2 are secured to the outer face of the window frame and extend outwardly from said frame.

Set into the `sas-h opening of the window frame ll is the sash `3 of the improved window Structure, said sash beingrectangular in shape and being composedo top, bottom, and side sash members hinge members 4, these hinge members being Y shaped in accordance with thehinge members 2 and being secured to the outer face of the window sash from which they extend outwardly. The upper pair of hinge members 2` and 4 and the lower pair of hinge members 2 and 4 are hingedly secured together for movement of the hinge members Al with respect to` the hinge members `2 by means of bolt and nut assemblies 5,. there being a washer 6 interposed between each related pair of hinge members, as is shown to good advantage in Fig.V 2. Also, it will be noted by referring `to Fig. 2, `that the `transverse legs 3c vof the window sash `3 are spaced inwardly from the transverse legs Ic of the window frame l when thewindow sash is in its closed position, 4and that at this time the legs 3b ofthe window `sash overlap and contact with the legs Ib of the. windowframe, while the legs 3a of the window sash contact with Ythe legs .la of the Window frame.

Supported in a vertical position for axial rotation at the right-hand side of. the window frame, as the window structure is illustrated in Figs. 1, 4, and 5, is an elongated tubular element l. rIhis tubular element extends from leg` le .of the vbottom window frame member to the leg lc of` the top window frame member, there` being supporting pinsS seated in said legs lc of said 4top and bottom window frame members and extended into` the opposite` vend portions of` the tubular element l, for supporting said tubular element for axial rotation.

. Welded, or otherwise secured to the` tubular element 'l atthe bottom thereof is a horizontal arm 9., said arm being disposed in the space between the lower transrerse leg tc of the `window frame l and the lower transverse leg c of the window sash 3. The arm 9 has formed integral therewith an arcuate handle element l0, the center of the curvature of said arcuate handle element being the center of the tubular element l, and said arcuate handle element extends through an opening l2 formed through the leg la at the bottom of the window frame l (Fig. 3) Pivotally attached tothe outer portion of the arm by means of a p ivot element i3 is an elongated connecting member Iii, the opposite end of said connecting member being pivotally attached by means of a pivot element l5 to an element l5 which is secured to the transverse leg 3a at the bottom of the window sash 3. In like manner, the tubular element l has welded, or otherwise secured to its upper portion an arm il which `is shaped as is the arm 9 with the exception that no arcuate handle element is extended therefrom. The arm Il is disposed between the upper transverse leg lc of the window frame i and the upper transverse leg 3c of the Window sash 3, and pivotally attached to the outer portion of the arm il by means of a pivot element i8 is an elongated yconnecting member i9. At its opposite end the connecting member i9 is pivotally attached by means of a pivot element 2@ to an element 2| which is secured to the upper transverse leg 3c of the window sash 3.

It is to be noted that outer portions of the arms 9 and il are provided with extensions 9' and Il' which are provided with inclined edges 22. Also, the window sash has secured to the inner faces of the legs 3b of said window sash located at the top and bottom of said window sash a pair of elements 23 which are provided with inclined portions 23 that are adapted to be engaged by the inclined edges 22 of the extensions 9 and il' of the arms 5 and il when the window sash 3 approaches its closed position and when said window sash is in its closed position (see Figs. 4, 5, and 6). These parts of the improved window structure provide the weather tightening means of the impro-ved structure which seal the window sash in weather-tight relation with respect to the window frame, and the precise operation of said weather tightening means will be hereinafter explained. Y

The arcuate handle element l0 is provided with a pivot element 24 which is secured to said arcuate handle element, a portion of said handle element being interposedbetween the head of the pivot element and a shoulder 24 formed thereon, as is shown in Fig. '7. The lower portion of the pivot element 24 supports a locking member 25 for pivotalmovement with respect to the arcuate handle element lil, saidrlocking member being provided with an opening through which the lower portion of said pivot element extends, and said pivot element 24 having an enlarged, annular, lower portion Zlla which extends beyond the pivot opening of said locking member. The locking member 25 is shaped approximately in accordance with the arcuate handle element li) that is to say it includes an arcuate portion 25a which underlies the arcuate portion of the handle element and a grip portion 25D which underlies a correspondingly shaped grip portion vI El formed 'on the handle element Ill. The pivot element 24 is provided with a narrow aperture formed therein in which is anchored a flat strip 26 of spring material, and the locking member has formed therein a narrow slot 2 into which this strip oi spring material extends. This strip of spring material retains the locking member 25. in the position with respect to the handle element [G irl which it is shown in Fig. 5 where the grip portion 25h of the locking member is offset slightly from the grip portion I5 or" the handle element and where the arcuate portion 25a of the locking member 25 is oilset slightly relative to the arcuate portion of the handle element lli. However, for a purpose to be explained later herein, the grip portions of the locking member and the handle element may be squeezed together to overcome the force exerted by the strip of spring material 25 and thus cause said grip portions of said locke ing member and handle element to be alined and to cause the arcuate portion of the looking member 25 to be alined with the arcuate portion of the handle element lil. The locking member has formed in an edge portion thereof a plurality of notches 2S which perform a function to be hereinafter set forth.

When the sash 3 of the window structure A is in its closed position with respect to the window frame l an edge portion of the locking member 25 is in engagement with an edge portion of the opening l2 formed through the leg la at the bottom of the window frame l as is shown in Fig. 5, whereby the sash is locked in its closed position. Also', in the closed position of the window sash the inclined edges 22 formed on the extensions 9 and il" of the arms 9 and Il are in close engagement with the inclined portions 23 of the elements 23, as is shown in Figs. 4 and 5, whereby the window sash 3 is held in weather tight contact with respect to the window frame I.

When it is desired to adjust the window sash 3 to an open position, the grip portions l0 and 25D of the handle element Iii and the locking member 25, respectively, are grasped and squeezed to cause said grip portions to be alined with respect to each other, and to cause the arcuate portion of the locking member to be alined with the arcuate portion of the handle element. The alined handle element and locking member may then be moved through the opening l 2 in the leg la at the bottom of the window frame i and such movement of said parts will subject the elongated, tubular element 'l to axial rotation. As a result of such rotation of the tubular element 'l the arms 9 and il will be swung outwardly, as indicated by dotted lines in Figs. 4 and 5, and the parallel connecting elements Id and I9 at the top and bottom of the sash will move said sash to an open position, as is also indicated by dotted lines in Figs. 4 and 5. When it is desired to lock the window sash in one of various open positions the handle element I and the locking member 25 are adjusted to a position where one o1" the notches 28 is alined with the edge portion I2 of the opening l2 formed through the leg la at the bottom oi the windov/ frame l. rThe grip portions l0 and 25h of the handle element i5 and locking member 25, respectively, are then released whereupon the strip of spring material 26 will move the locking member out of alinement with respect to the handle element so as to cause the alined notch of the locking member to embrace the edge portion i2 of the opening l2 and thereby effect locking of the sash in anopen position, as is shown in Fig. 6.

It is to Ybe noted that as the window sash is being moved toward its closed position with respect to the window frame, the inclined edges 22 of the extensions 9 and I1 of the arms J and I'I' approachv and nally engage the inclined portions 23 of the elements 23 just prior to final closing movement of the sash. This results in the window sash being weather tightened during final movement of the sash to its closed position with respect to the Window frame, as the rlal movement of the handle element lll will draw the sash into tight contact with the frame because of the cooperative engagement of the extensions 9 and Il of the arms 9 and I l, and the elements 23.
